IMPROVEMENT IN HAME-TUG LooPs.

Specification forming part of Letters Patent No. 216,618, dated J unc17, 1879; application filed May 7, 1879.

To all whom it may concern Be it known that I, JAMES M. JOHNSON, of

the city of Niles, in the county of Berrien and State of Michigan, have)nvented certain new and useful Improvements in Hame-Tug Loops; and I dohereby declare that the following is a full, clear, and exactdescription thereof,

- reference being had to the accompanying drawings, and to the lettersof reference marked thereon, which form a part of this specification.

I My invention relates to a metal tilting loop, intended to be appliedto the haine-tugs of heavyharness to receive the ends of the drafttugs,which, because of their extreme thickthe hame-tug or increasing theentrance-opening beneath the same, and thereby enabling the trace ordraft-tug to be more easily inserted under the loop; and also in makingthe pivotal bar upon which the loop swings contin nous and solid withthe loop itself, in order to prevent the latter from being detached ordrawn awayfrom the hame-tug by any of the severe strains put upon itfrom the catching of the free or exposed end of the draft-tug, whichstrains are common with this class of harness.

Figure 1 of the drawings shows, in perspective, my improved loopdetached. Fig.2 is a transverse section of the loop, showing the same inan upright position and applied to a hame-tug, which is shown inlongitudinal section. Fig. 3 is a corresponding section of the sameparts, showing the loop in a tilted position or resting at one marginupon the hametug. Figs. 2 and 3 are arranged on the same horizontal linein the drawings, for the purpose of more clearly showing by the severaldotted lines the relative increase in the height of the opening whichresults from the. addition of .the lateral wings to the top when theloopis tilted. Fig. 4 is a top view of the winged plate of the loop.

T is intended to represent the top plate of a loop of the common widthor of the greatest width hitherto known in harness-loops, or

that portion of the top plate in the figures tical sides of the loop,continuous with the top late and B is the solid or continuous cross- 1 7bar, cast in a single piece with the other parts mentioned.

The distinctive or more important characteristic of my improved loop isthatwhichrelates to the wings W, whereby when a loop is applied tot-hehame-tug or straight strap, as shown in Figs. 2 and 3, the openingbeneath it is made greater the farther the loop is tilted. Said Figs. 2and 3 are intended to show the height of the loop, the space beneath it,and the breadth of the winged top in about the proper relativeproportions.

It is made obvious by means of the dotted lines a b and c d that theentrance beneath the loop is very materially increased by-nieans of thewings, for not only does the wing which rests upon the hame-tug supportthe top plate proper at a material elevation, but it equally supportsthe opposite wing also, which of itself forms a guide to direct thetrace into the space beneath the loop. The actual height of theeffective entrance is, therefore, measured by the line a 01, while theheight of the erect loop is measured by the line 0 b.

It is obvious from Fig. 3, without the aid of further lines, that ifboth wings were removed the opening or entrance would be materially lessthan that presented by the vertical loopi The special utility of mydevice becomes apparent if we attempt to insert beneath the loop a traceof the thickness of c b, which is the exact height of the entrancebeneath the loop when vertical, as seen in Fig. 2. It is at once evidentthat thiscan be done far more readily when the loop is tilted, as shownin to be applied, it is common for the end of the.

draft-tug which protrudes through the hametug loop to catch againstfences, posts, or other similar obj ects. Leather loops are there byoften soon turned or ripped away, and the metal loops in which thecross-bar is not continuous and cast of a piece with the sides, sincethe cross-bar is necessarily small, are only less easily detached. Onthe other hand the loop formed as herein shown is able to re sist allstrains'to which they are commonly subjected, and the cross-bar. at thesame time may be of only convenient size.

Having thus described my invention, I claim as new- A pivoted or tiltingharness-loop cast in one piece with the continuous crossbar B, andprovided with the lateral top wings W W, substantially as and for thepurpose set forth.

In testimony that I claim the foregoing as my invention I affix mysignature in presence of two witnesses.
